This is one of the best interviews that i've seen with Ritchie. He talks fantastically about
6 Deep Purple songs. And he explains how, when, from where, from what they became,
with fabulous examples after each song, made by Japanese interviewers. The songs are:

Mandrake Root
Black Night
Speed King
Smoke On the Water
Lazy
Highway Star

Pay attention at the end when he talks about Highway Star, and mentions Gillan and what

he says about him !

Believe me you can't often hear Ritchie talking about Ian in that way !
